[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of a seepage-proof structure for water supply and drainage engineering, including a connecting sleeve 1. A fixing sleeve 2 is fixedly connected to the inner wall of the connecting sleeve 1. The middle part of the fixing sleeve 2 is hollow, allowing sewage to flow from the fixing sleeve 2 through a conical barrel 5 into a pipe 7. A contact block 4, made of rubber, is elastically connected to the inner wall of the left end of the fixing sleeve 2 via a return spring 3. The contact block 4 can be inserted into the side wall of the pipe 7 to ensure its sealing. A conical barrel 5 is fixedly connected to the side wall of the right end of the fixing sleeve 2. A rubber block 6, also made of rubber, is fixedly connected to the outer wall of the conical barrel 5, allowing the rubber block 6 to engage with the pipe. The contact of the 7-channel increases the sealing effect. The inner wall of the connecting sleeve 1 is inserted with a pipe 7. There are two sets of pipes 7, which are distributed on both sides of the connecting sleeve 1. The left pipe 7 is the water inlet pipe, and the right pipe 7 is the water outlet pipe. The outer wall of the connecting sleeve 1 is fixedly connected with a U-shaped plate 8. The inner wall of the U-shaped plate 8 is provided with a limiting mechanism. The inner wall of the connecting sleeve 1 is provided with a flipping component. The limiting mechanism includes a wedge 10. The wedge 10 is inclined. When the inclined surface is squeezed, the wedge 10 will slide along the inner wall of the U-shaped plate 8. The wedge 10 penetrates and slides on the inner wall of the U-shaped plate 8. The inner side wall of the wedge 10 is elastically connected to the U-shaped plate 8 through a positioning spring 9.

[0034] Reference Figure 3 , Figure 5 and Figure 6 The inner wall of the connecting sleeve 1 is elastically connected to a fixed shaft 11 via a torsion spring 12. A rotating plate 13 is fixedly connected to the bottom end of the fixed shaft 11. A positioning plate 14 is fixedly connected to the inner wall of the connecting sleeve 1. The positioning plate 14 can block the rotating plate 13 from rotating clockwise. The fixed shaft 11 is rotatably connected to the inner wall of the connecting sleeve 1. The connecting sleeve 1 has a slot, which allows the fixed shaft 11 to rotate counterclockwise without affecting its movement trajectory. The inner wall of the connecting sleeve 1 is fixedly connected to one end of the torsion spring 12. When the fixed shaft 11 rotates, it will compress the torsion spring 12. When resetting, the elastic force of the torsion spring 12 will carry the fixed shaft 11 back to its original position. The other end of the torsion spring 12 is fixedly connected to the outer wall of the fixed shaft 11. The inner wall of the connecting sleeve 1 is in contact with the side wall of the rotating plate 13. The outer wall of the rotating plate 13 is in contact with the right outer wall of the positioning plate 14. The contact between the rotating plate 13 and the connecting sleeve 1 can prevent sewage backflow.

[0035] Reference Figures 2-4 The inner wall of the left end of the fixing sleeve 2 is fixedly connected to one end of the return spring 3, such as... Figure 4As shown, the return spring 3 is in a compressed state at this time. When the contact block 4 is not in contact with the side wall of the pipe 7, the elastic force of the return spring 3 will cause the contact block 4 to return to the right. The other end of the return spring 3 is fixedly connected to the left end of the contact block 4. The contact block 4 is slidably connected to the inner wall of the fixing sleeve 2. The right end of the contact block 4 is inserted into the side wall of the pipe 7. The side wall of the pipe 7 has a slot, which is the same size as the contact block 4, allowing the contact block 4 to be inserted into the slot. The right end of the fixing sleeve 2 is connected to the side wall of the pipe 7. When the surface of the rubber block 6 contacts the inner wall of the pipe 7, the inner side wall of the wedge 10 is fixedly connected to one end of the positioning spring 9. When the wedge 10 moves outward, it will compress the positioning spring 9. When resetting, the elastic force of the positioning spring 9 will bring the wedge 10 back to its original position. The other end of the positioning spring 9 is fixedly connected to the inner side wall of the U-shaped plate 8. The wedge 10 is inserted into the outer wall of the pipe 7. The pipe 7 has a slot corresponding to the wedge 10, which allows the wedge 10 to be inserted into it to limit the one-way movement of the pipe 7.

[0036] Working principle: First, when it is necessary to disconnect the pipe 7, simply pull the wedge 10 outward and compress the positioning spring 9 to separate the wedge 10 from the groove on the outer wall of the pipe 7. Then, move the pipe 7 out to the right from the inner wall of the connecting sleeve 1. At the same time, the groove of the pipe 7 separates from the contact block 4. The reverse elastic force of the return spring 3 will reset the contact block 4, and the rubber block 6 will disengage from the pipe 7. Finally, release the wedge 10 and reset the wedge 10 using the positioning spring 9.

[0037] When pipe 7 needs to be installed, simply insert pipe 7 into connecting sleeve 1, allowing the left end of pipe 7 to press against the inclined surface of wedge 10, causing wedge 10 to move outward and stretch positioning spring 9. When the groove of pipe 7 and wedge 10 coincide, the positioning spring 9 will use its own elasticity to reset wedge 10, allowing wedge 10 to be inserted into the groove of the outer wall of pipe 7. This will cause the inner wall of pipe 7 to contact rubber block 6, forming a preliminary seal. After pipe 7 enters connecting sleeve 1, the groove of the side wall of pipe 7 will be inserted into contact block 4 and compress the reset spring 3. The reverse elasticity of reset spring 3 will allow contact block 4 to remain inserted into the groove of the side wall of pipe 7, forming a second layer of seal, completing the entire sealing process and preventing sewage leakage.

[0038] During use, the device allows sewage to enter the connecting sleeve 1 from the left end pipe 7. The water flow impact causes the rotating plate 13 and the fixed shaft 11 to rotate counterclockwise and compress the torsion spring 12, allowing the sewage to flow out from the pipe 7. When there is no sewage, the reverse elastic force of the torsion spring 12 will reset the fixed shaft 11 and the rotating plate 13, which can prevent sewage backflow and leakage.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
